Perfex CRM Module for Zadarma Integration

I am seeking a proficient developer to create a module to smoothly integrate zadarma.com services into Perfex CRM. A candidate’s experience with both Zadarma and Perfex CRM will be crucial to ensure a successful development of this module. This project will be the first version and will primarily focus on outdoing calls.
